Testo 440 delta P Air Flow ComboKit 2 with Bluetooth®

Intuitive: clearly structured measurement menu for volume flow and parallel determination of air velocity, differential pressure, humidity and temperature in ventilation ducts, at ventilation outlets and in work rooms

As multifaceted as your challenges themselves: the Testo 440 dP has an integrated differential pressure sensor and can be expanded with a large portfolio of digital probes

Carry out measurements without any annoying cables: use the kit to handle all relevant measurements in ventilation ducts and at air/ceiling outlets. You will receive the Testo 440 dP air velocity and IAQ measuring instrument including differential pressure sensor, two vane probe heads (Ø 100 mm and Ø 16 mm) and a humidity/temperature probe head – all three can be attached to the universal Bluetooth handle supplied. To make measurements more convenient, both vane probe heads can be combined with the telescope included in the kit. The equipment can be transported safely and conveniently in the robust case.

Product DescriptionCarry out measurements without any annoying cables thanks to the universal Bluetooth handle: use this practical kit to handle all relevant measurements in ventilation ducts, at air/ceiling outlets and in offices. The Testo 440 dP multi-function measuring instrument, the vane probe, the 16 mm vane and humidity/temperature probe head all feature an intelligent calibration concept, ease of use and maximum convenience for the adjustment of air-conditioning and ventilation systems.

No task is too challenging, no application too specialized: the Testo 440 dP combines a compact hand-held measuring instrument with intuitive measurement menus and a wide selection of air velocity and IAQ probes (please order separately)

Clearly structured measurement menus for carrying out measurements in ventilation ducts and at duct/ceiling outlets: the volume flow is precisely calculated thanks to convenient input of the size and geometry of the duct cross-section. Timed and multi-point mean calculation, average volume flow, current reading and min./max. values are displayed

Easy storage and evaluation of measurement data. Measurement data memory for up to 7500 measurement protocols, which can be read via a USB port and further processed as a CSV file on the computer (e.g. with Excel)

Use the vane probe (Ø 100 mm) to conveniently determine air velocity, volume flow and air temperature at air/ceiling outlets

Measuring range: +0.3 to +35 m/s, -20 to +70 °C

More applications – less equipment: the universal handle on your 100 mm vane probe is easy to attach to other probe heads or telescopes. This allows you to expand your portfolio of probes and save space in the measuring case

Carry out measurements at air/ceiling outlets effortlessly and without using a ladder: simply connect the vane probe to the extendable telescope with 90° angle included in the kit

Wireless: the Bluetooth handle makes it more convenient to carry out your measurements and guarantees less cable clutter in the case

Practical button on the handle: to store individual readings for multi-point mean calculation or to start and stop measurement series for mean calculation over time

Our recommendation for carrying out accurate measurements at plate outlets/ventilation grilles: use the vane probe with the Testovent 417 funnel set (available to order separately). If you add in the volume flow straightener (please order separately), you can achieve an impressively high level of precision when carrying out measurements at swirl outlets with turbulent air flow

Intelligent calibration concept: the air velocity and IAQ measuring instrument remains in continuous use, since only the probe head is sent in for calibration

16 mm vane probe head including temperature sensor:

Use the vane probe (Ø 16 mm) to determine the air velocity, volume flow and air temperature in ventilation ducts

Measuring range: +0.6 to +50 m/s, -10 to +70 °C

Convenient measurements in ventilation ducts: the probe head is easy to attach to the robust, non-rotatable telescope (up to 1.0 m) supplied, with easy-to-read scaling and Bluetooth handle

Practical button on the handle: to store individual readings for multi-point mean calculation

Our recommendation for larger ducts: use the telescope extension (available to order separately) – enabling you to attain a total length of 2 metres

Intelligent calibration concept: only the 16 mm vane probe head needs to be sent in for calibration

Humidity/temperature probe head:

Use the humidity/temperature probe to accurately measure relative humidity and air temperature and to calculate dew point, wet bulb temperature, absolute humidity and heating/cooling output

Convenience and maximum flexibility for duct and outlet measurementsUse our large range of air velocity probes (please order probes that are not included in the kit separately) to carry out simple, convenient measurements even at locations that are difficult to access in ventilation ducts or at air outlets:

You can even carry out easy measurements in particularly large ducts. This is because the extendable telescope on the hot wire and vane probe (Ø 16 mm) with universal handle can be further extended using the telescope extension – enabling you to attain a total length of 2 metres.

Carry out measurements at air/ceiling outlets effortlessly and without using a ladder. Fit your vane probe (Ø 100 mm) with the telescope with 90° angle and, if necessary, with the telescope extension (both can be ordered separately).

Greater freedom thanks to Bluetooth: the air velocity probes with Bluetooth have no inconvenient cable connection to the measuring instrument, and they transmit readings up to a distance of 20 m. Press the button on the probe to operate the measuring instrument – for example, to start and stop a series of measurements (timed mean calculation).

Benefit from fast calculation of the volume flow: in the “volume flow” measurement menu of the multifunction measuring instrument, configure the dimensions and geometry of the duct cross-section – the measuring instrument shows you the volume flow straight away

Long-term monitoring of indoor air qualityPoor indoor air quality due to excessive concentrations of CO2 can cause tiredness, lack of concentration and even illness. With its menu for recording readings, the Testo 440 air velocity and IAQ measuring instrument is ideal for monitoring the indoor air quality. Enter the measurement time and the measuring cycle – and, for example, track the change in CO2 concentration or humidity and temperature values over the course of the day. Simply choose between probes with Bluetooth or fixed cable for CO2, CO or humidity (please order probes separately).

Turbulence measurement in accordance with EN ISO 7730 / ASHRAE 55Determine the degree of turbulence and the draught risk in the workplace: draught restricts the comfort level and is the most common cause of complaints about the indoor climate. The turbulence probe (please order separately) measures air velocity and air temperature, and automatically calculates the draught risk and the degree of turbulence in accordance with EN ISO 7730/ASHRAE 55.For convenient measurements at varying heights, we recommend using our measuring tripod for comfort level measurement (please order separately). This makes it very easy to position turbulence probes in compliance with the standards.

Range of probes for cleanrooms and laboratoriesThe Testo 440 air velocity and IAQ measuring instrument is also ideal for a wide variety of applications in cleanrooms and laboratories in conjunction with the following probes (please order separately):

High-precision air velocity measurement on fume cupboards with the fume cupboard probe

Thanks to the low start-up speed of 0.1 m/s, the high-precision vane probe (Ø 100 mm) is ideal for laminar flow measurements in cleanrooms. It is available as a variant with Bluetooth or with fixed cable

To measure the humidity in cleanrooms, we recommend the high-precision humidity/temperature probe (0636 9771 or 0636 9772). With an accuracy of: ±(0.6% RH + 0.7 % of m.v.) (0 to 90% RH), it also meets the requirements for humidity measurements in this particularly sensitive area
